The invention is described more fully hereinafter with reference to theaccompanying drawings, in which embodiments of the invention are shown.This invention may, however, be embodied in many different forms andshould not be construed as limited to the embodiments set forth herein.Rather, these embodiments are provided so that this disclosure isthorough, and will fully convey the scope of the invention to thoseskilled in the art. In the drawings, the size and relative sizes oflayers and regions may be exaggerated for clarity. Like referencenumerals in the drawings denote like elements.

A mobile communication terminal as used throughout the presentspecification may be, for example and without specific limitation, acomputer, a public switched telephone network (PSTN) terminal, a voiceover Internet protocol (VoIP) terminal, a session initiation protocol(SIP) terminal, a media gateway control (Megaco) terminal, a personaldigital assistant (PDA), a mobile phone, a personal communicationservice (PCS) phone, a hand-held personal computer (PC), a Code DivisionMultiple Access (CDMA)-2000 (1X, 3X) phone, a Wideband CDMA (WCDMA)phone, a dual band/dual mode phone, a Global System for MobileCommunications (GSM) phone, a mobile broadband system (MBS) phone, or asatellite/terrestrial Digital Multimedia Broadcasting (DMB) phone.

FIG. 2 is a diagram illustrating a configuration of a mobilecommunication terminal 200 according to an exemplary embodiment of thepresent invention.

As illustrated, the mobile communication terminal 200 may include adisplay module 210, a display control module 220, a storage module 230,an input module 240, an input sensor 250, and a data configurationmodule 260.

The display module 210 may display image data, generated via a camera orreceived from another mobile communication terminal, such as by MMS, onan image display area. The image data may be a still image or picture,or video or moving images, taken via a camera installed in the mobilecommunication terminal 200 or received from another mobile communicationterminal, such as by MMS. Alternatively, the image data may be adocument with characters, with or without images, in anapplication-specific format, such as pdf, or in an image format, such asJPEG. The image data may be captured by the mobile communicationterminal, or may be received at the mobile communication terminal byMMS, through an email server and an email application on the mobilecommunication terminal, through an internet application on the mobilecommunication terminal, or through any other wireless or wired datatransfer mechanism, including without limitation a device-to-devicetransfer mechanism, such as a short range wireless communication moduleincluding an Infrared Data Association (IrDA) module or a Bluetooth®module. The image display area may be an area displaying images on ascreen.

The input module 240 may generate touch data according to a touch inputin a touch area corresponding to the image display area. The touch areamay include all of the image display area. That is, to receive the touchdata from a user, the touch area may be arranged to correspond to theimage display area. As an example, the touch data may be any graphicaldata, including characters, figures, pictures, emoticons, diagrams andthe like, and may be inputted via various devices such as sticks or astylus, pens, fingers, and the like. The user may also select otherfeatures of the touch data, such as color or thickness.

For this, the input sensor 250 may calculate coordinate informationabout a point or series of points where the touch input is received inthe touch area. The coordinate information may be specific informationabout where the touch data is inputted on the touch area, and, based onthe coordinate information, includes a location where the touch data isto be displayed and/or data about whether the touch data corresponds toone of characters, pictures, diagrams, figures, and emoticons.

The data configuration module 260 may generate the touch data based onthe calculated coordinate information. Also, the data configurationmodule 260 may obtain time information of a time when the touch input isreceived, and may associate the touch data with the image data based onthe obtained time information and the coordinate information.

That is, by associating the touch data along with the image data basedon the time information and the coordinate information, when the imagedata is played back or retrieved or selected to be displayed on themobile communication terminal 200, the data configuration module 260enables the touch data to be displayed on the display module 210 alongwith the image data at a time during the playback corresponding to atime when the touch data is inputted. As an example, if five minutes ofvideo as image data is generated, and touch data of ‘DUMMY’ is inputtedat a time of two minutes thirty seconds into the generation or playbackof the video, the data configuration module 260 may mix the touch datawith the image data representing the video at that time and the displaymodule 210 will display the touch data of ‘DUMMY’ at two minutes andthirty seconds when next playing back the video.

If the touch input moves over the touch area, the data configurationmodule 260 may generate touch data having a shape that corresponds tothe movement of the touch input.

If the display module 210 provides an emoticon via the image displayarea, a user may select an emoticon, and thereafter the input module 240may generate a selected emoticon as the touch data.

The storage module 230 may store the generated touch data along with theimage data. That is, the storage module 230 may store the touch dataincluding the time information and coordinate information as dataassociated with the image data. Throughout this specification, the touchdata is described as data “associated with” the image data, and thisdescription is intended to cover many different storage options. Onestorage option is that the touch data may be stored separately from theimage data, as a separate file, but that data associating the image dataand the touch data will also be generated and stored. In this manner,the storage module 230 may be able to retrieve the image data in a firstformat with the touch data or in a second format without the touch data.Alternatively, another storage option is that the touch data is storedas embedded data in the image data, and that the touch data and imagedata are stored as a single file in the storage module 230. The singlefile may be encoded and/or compressed. Depending on the storage scheme,a user of the mobile communication terminal may select image data, touchdata, or a combination thereof to send to another mobile communicationterminal by, for example, MMS. Then, a user may send image dataincluding touch data, or may send either image data or touch dataseparately.

The display control module 220 may control the touch data to bedisplayed on the image display area along with the image data. That is,the display control module 220 may control the image data to beassociated and displayed with the touch data.

FIG. 3 is a diagram illustrating an example of generating image data inthe mobile communication terminal 200 of FIG. 2.

As shown in a reference numeral 310, the mobile communication terminal200 may receive the touch data of ‘DUMMY’ from the user in the toucharea and display the touch data on the image display area. The user mayinput the touch data of ‘DUMMY’ using fingers, stylus or sticks, pens,and the like. The mobile communication terminal 200 may store the touchdata of ‘DUMMY’ in the storage module 230 by associating the touch datawith the image data based on the time information when the touch data of‘DUMMY’ is inputted and coordinate information corresponding to alocation on the image data where the touch data is input on the imagedisplay area.

Alternatively, as shown in a reference numeral 320, the mobilecommunication terminal 200 may receive an emoticon, heart shapes in thisinstance, as touch data when the touch data is generated. If theemoticon is generated as touch data, when the user selects the emoticonand selects a point where the emoticon is to be located, the mobilecommunication terminal 200 may display the emoticon on the establishedcoordinates where the emoticon is to be located. As explained above, themobile communication terminal 200 may store the touch data byassociating the touch data with the image data in the storage module230. In this instance, the touch data will include the type of emoticon,the time information, and the coordinate information.

As an example, the mobile communication terminal 200 may provide a listof possible emoticons, permit a user to select one or more emoticonsfrom the provided list of emoticons, and generate the selected emoticonas touch data when the touch input is received. Thus, the user maycreate or receive new emoticons to add to the list, and revise or deleteexisting emoticons from the list of emoticons.
